                    Sexual Reproduction in Plants

                    In sexual reproduction, two parents (male and female) are involved in producing a new

                    individual. Male and female reproductive cells (called gametes) combine to form a single
                    cell called zygote. The zygote divides to form a multicellular structure called embryo.
                    Embryo develops into a new individual. In plants, embryo formed as a result of sexual

                    reproduction is present inside the seed.

                    Stamen is the male reproductive part of a fl ower.  Anther
                    in a stamen produces pollen grains. Pollens contain male

                    reproductive cells.                                                        fi lament
